To all whom it may concern.'

Be it known that 1, Gaone KIRWEGAARD, a -citizenof the United 'Stat-es, and a resident of the ity ci New York, in the county of New York and State of New York, Unitedl States of America, haye invented certain new and useful lm rovements in Bottle- Capping Machines, -o which the following is a specification.

My invention relates to a bottle capping machine and its object is to provide a simple apparatus for securing bottle Stoppers or c sl over the mouths of bottles.

will describe my invention in the following specification and point out the novel features thereof in claims.

Referring to the drawings, Figure 1 shows, in side elevation, my improved bottle capping machine. Fig. 2 is a front sectional elevation of some of the parts shown in Fig. 1. Fig. 3 is a side sectional elevation of some of the parts shown in ig. .2, showing these arts 1n different relative positions. Fig. 4 1s a plan view of a forming ring which l use in carrying out my invention. Fig. 5 is a side elevation, partly in section, illustrating a modiication of my invention.

Like characters of reference designate corresponding parts in all of the iigures.

10 designates a base upon which the;

various parts of my machine are mounted. 11 is a standard securely attached to this base. This standard 11 is provided with a slot 12.

13 designates a supporting-head or carriage which is slidably mounted upon the standard 11 and which may be secred to the standard 11 at any desi/red position by means of lock-nuts 14, 14.

15 designates a lever which is pivoted to the carriage 13 at 16 and which is normally held in a. raised position, as shown in Fig. 1,

by means of a retractile spring 17. The:

lever 15 is provided with slots v18 which are arranged to engage with trunnions 26, 26.

20 designates a shaft which is supported by the head or carriage 13 and which is arranged to move vertically in said head. The lower portion of this shaft 20 is provided with an enlarged portion 21, the bottom of which isenlarged to a still greater diameter as shown at 22. This shaft 20is preferably constructed ef hardened steel and may be magnetized so that it forms a permanent magnet. 1

23 designates a sleeve which is loosely mounted on the shaft 20 near its upper end. The lower end of this sleeve is enlarged to form a shoulder 24.

25 designates a ring which is attached to the sleeve 23 and which carries upon it trunnions 26, 26.

27 is a collar rigidly attached to the upper part of the shaft 20 and arranged to limit the upward movement of the sleeve 23 on the shaft 20. Y

30 designates a plunger-head. The upper portion of the plunger-head 30 is bored out, as shown at 32, to a diameter slightly' larger than the diameter of the portion 21 of the shaft 20, and the lower portion of the plunger-head is bored out, asshown at 33, to a diameter somewhat larger than the portion 22 of the shaft 20. These two portions will form between them a shoulder 34.

35 is a. collar which yis arranged to he secured onto the bottom of the plunger-head, and this collar is provided with a shoulder 36.

37 designates a main compression Spring which is placed about the shaft 20 and between the portion 21 and the lower portion 24 of the collar 23.

38 designates an auxiliary compression spring which is placed about the portion 2l of the shaft 20, and between the portion 22 of the shaft 20 and the shoulder 34 which is formed inside of the plunger-head 30.

steel or other suitable material. This ring 4is provided with a shoulder 41 and a formingsurface 42. It may, if desired, be s llit as shown at 43 by a radially dispose slot. This forming-ring is arranged to be held by the plunger-head 30 between the bottom of the plunger-head and the upper ortion of the shoulder 36 on the collar 35. his collar may be screwed onto the plunger-head 30 a Sutticient amount to support the formingring 40, but still, not screwed on tight' enough to prevent a limited movement of the forming-ring between the plunger-head and the collar 50 designates a bottle which is provided near its upper end with an annular rim or shoulder 51.

19 is a guide for the bottle which is supported upon .the standard 11 by means of a set-screw 19^.

designates a cap which is ada ted to tit I over the top of the neck of theottle 50. g This cap is provided with depending fingers i 61, which fingers are arranged with project- 40 designates a forming-ring of hardened movement o ing portions 62 upon which the forming-ring acts, as will appear later.

63 designates a packing of cork or other resilient material which may be placed within the cap 6U before the cap is placed upon the bottle. These caps are preferably contructed of magnetic materia such, for example,

as commercial tin, which is a sheet of iron coated u ith metallic tin.'

The operation of this device is as follows: A bottle 50 is placed upon the base 10, and

the guide 19 is so adjusted as to hold this bottle in alinement v; it i the center of shaft 20.

The supporting-head or carriage 13 is then .end of the shaft or plunger. he operator may then pull the lever 15 downward and thereby cause the loose sleeve 23 to move. This downward movement will be transmitted to the plunger-head 30 and to thc shaft, which arey resiliently connected together and to the loose sleeve by means of thesprings 38 and 37. The parts will travel downward together until the cap 60 rests upon the top of the bottle 50. A further `the lever 15 and the shaft 20 will cause the cap and its resilient packing to be compressed against the top of the bottle with a pressure depending u on the strength of the spring 37. A still furt er movement of the lever 15 and loose sleeve 23 will cause the lower part 24 of this sleeve 23 to be brought against the upper part 31 of the plunger-head 30, and will cause the lo'ose. sleeve 23 and the plunger-head 30 to be positively moved downward together. This will cause 1 the forming-ring 40 to be moved down past the top of the bottle, and its forming surface 42, enga ing-with the projecting portions 62 ou the epending fingers 61 of the cap 60, w ill cause the latterrto be bent inward about' the annular rim or shoulderl on the bottle. This will cause the ca vto be securely -fastened to the bottle, an( it will remain in this` 'position when the operator releases the lever 15 and allows the retractile spring 17 to vmove the lever and its connected parts upward again.

A screw 12 ma be placed through the head 13 and the s ot l2 and this will limit the movement of the head on thes'upport 11 and help to guide the head when it is moved upon the standard 11.

The forming-ring 4Q may be split as at 43 for the purpose of preventing the ring from breakin` such bottles as may be of a slightly larger 'ameter than those for which it 1s adapted The ring may be loosely mountedv sangen in the end of the lunger-head, in a manner previously described, for the purpose of adapting itself'to the position of the bottle.

In Fig. 5 I have shown another form of my invention, in which case the formingring 40'* is screwed directly into a plungerhead 30A. This plunger-head is supported and uided by a traveling-head or frame 13^ w 'ch is mounted uponthe standard 11 in the manner previously described.

A lever 15^ .1s pivoted to the head 13A at 16^ and is connected to act directly upon the plungerheadl 30^. A shaft 20* is placed within this plunger-head 0^ and connected to it by means of a spring 88*, one end of which spring rests upon an enlarged portion 22'* of the shaft 20^ and the other end of which rests upon the upper end of the langer-head 3()^. The lever 15A may be eld in its upper position by means of a spring 17*. After a cap 60 has been placed upon the end ofthe enlarged portion 22* of the shaft 2()^, the a paratus may be operated in a manner simi ar to that previously described. In this case, when an operator depresses the lever 15A he will thereby positively move the plunger-head 30A and the forming-ring 40A downward and will, at the same time, depress the shaft 20A Athrough the spring 38A. The cap will thusxbecome pressed down upon the to of the bottle and the movement of the s aft 20'* Will thereby become arrested. A furtheremovement of the lever 15A will cause the forming-ring 40A to be moved down past thecap 60 and will cause the latter to e secured to the bottle.

designates an electric battery or some other source of electrical sup ly.

7.1 designates a coil or wind2 72 designates a switch whereby the battery may be connected to the coil71. When tlus is one a current-will be sup lied to the coil 71 and it will cause the s aft 20A to be magnetized thereby. This yis one method for magnetizing the shaft for the purpose of causing it t'o hold the cap60, which 1s preferably constructed of magnetic material. The' shaft, however, may bel made of hardened steel and may be permanently magnetized if desired` I have' shown this apparatus in two forms adapted'to be operated by hand, or,` it is obvious that it may be operated by footpower or b any desirable mechanical motive power.. T lese two, forms which I have shown clearly illustrate my invention, but it ma of course, be made in many other forms. wit out departing from the spirit of this invention.

' It is evident that the apparatus is adaptable for use with different sizes and shapes of bottles, as the guiding bracket 19 and the supporting-head or carriage 13 are adjustmg which may be placed aboutthe shaft 20'".

with a 'bottle cap,

Athe shaft and plunger-head,

able upon the standard 1]. The formingring 4() is separate from t-he rest of the apparatus, and a different size or shape of forming ring majv be substituted for it whenever desired.
